Absolutely fantastic game idea my dude. Ran smoothly and only had 1 minor issue with the enemy models being pushed outside the map. 40 rounds later and had no issues. This game could actually be up there with Balatro or cloverpit for sure.
Some things to add if you're looking for additional bits would probably be:
A speed up meter to allow rounds to go faster.
To increase difficulty an armor, penetrate dice roll or block healing dice roll for the enemies, as if you just stack armor or health its near impossible to lose.
Yellow ball might be a little too powerful still.
Also, if you were to add some character customization or cosmetics that would be sick!
Overall man 10/10 for gameplay and idea, will genuinely be watching this game for a while to see how it grows!
Cheers man all the best!
